The origin of spandex fiber
Fabric hotspots

Spandex fiber is a type of elastic fiber, commonly known as Spandex in foreign countries and spandex in China. However, in reality, spandex is only a major category of elastic fibers. There are two types of spandex fibers, one is a polyester spandex made of aromatic diisocyanates and polyester segments containing hydroxyl groups, abbreviated as polyester spandex, and the other is a polyether spandex made of aromatic diisocyanates and polyether segments containing hydroxyl groups, abbreviated as polyether spandex. The representative product name for polyester spandex is Vyrent, and the representative product name for polyether spandex is Lycra

Main properties of spandex fiber
Fabric hotspots

The main properties of spandex fiber are: it usually has an elongation of 500% to 700% or more, and good elastic recovery performance. At 200% elongation, it shrinks by 97%, and at 50% elongation, it shrinks by over 99%. The relative density difference of various spandex is relatively small, generally ranging from 1.20 to 1.25, with a fracture strength of 4.41 to 8.82cN/tex (0.5 to 1. Og/denier). Polyester spandex has lower strength, while polyether spandex has higher strength. The moisture absorption rate is generally 0.3% to 1.2%, and the moisture absorption rate of multifilament is slightly higher than that of monofilament. It is heat-resistant and can be stored for a short time at 95-150 ℃ without damaging the fibers. The safe ironing temperature is below 150 ℃. Fibers burn slowly and form a gelatinous residue after combustion. Excellent dyeing performance, capable of dyeing multiple colors, and strong affinity for dyes. Good acid and alkali resistance, can bleach, and does not mold
